They have completed designs using low enriched Uranium. They're not quite as elegant or as small, but they should work fine. https://fas.org/nuke/space/leu-reactor.pdf
It still produces a fair bit of alpha, so avoid particulate ingestion.
Several orders of magnitude less than Chernobyl. The reactor that lost containment was a gigawatt production plant. A gigawatt nuclear ramjet would be so huge there would be no trouble detecting it and shooting it down…
My local utility charges users $5,000 per installed pole for last mile connection. I've priced poles and wire, they are turning a hefty profit for last mile connections.
> Bringing from Earth a few tons of nuclear-powered jet engine to use water as propellant would take building such an engine first. We're not even close. True, but small scale solar thermal propulsion systems have been…
I am not sure if any of these programs are still around, but older, generic forms of insulin are available for free or greatly reduced price at many pharmacies to qualified applicants. http://www.needymeds.org/ Is a…

Falcon 9 was designed to be human rated, hence the Dragon capsule. The lag in certification is probably largely due to Russian/USA politics.
> "gee, look how wrong these other stats are" I get the feeling that the 1% knows how to hide their wealth from the IRS.
Fertilizers in general aren't necessarily bad. It is important for us to actively recycle our phosphorous and potassium, because there is no short term replenishment of these vital elements in the soil. For more…
The vast majority of nitrogen fertilizers are produced by burning natural gas with atmospheric nitrogen to produce NH3, NH3OH and CO2. https://en.wikipedia.org/wiki/Haber_process I guess in a way, the natural gas…
Thank you. I will definitely look into this. At the very least, it still makes an effective and fairly high nitrogen organic fertilizer, while drawing down atmospheric CO2. It's so effective at harvesting CO2, ancient…
A substantial fraction of the world's natural gas is burned to produce nitrogen fertilizer. This is largely obtained through fracking. Fertilizers, as they are used on the large scale, are pretty bad for the environment.
Been there, done that and have read dozens of research papers on azolla as livestock feed, but there hadn't been any human research when I delved into the subject. That was quite a few years ago, however. I'll dig back…
Fry are typically separated from the larger fish with netting. Sure, you could keep them all together, but a huge amount of system resources will be consumed by the endless cycle of breeding and cannibalizing and you…
Good to know about the possible neurotoxin. Any suggestions for further information on the topic?
Duckweed is a good tilapia feed, but requires a nitrogen source. Use it to supplement azola, it has around 4% more protein. The problem with tilapia is they reach breeding size long before they reach useful eating size.…
Azolla = free fish food. It obtains both nitrogen and carbon from the air and can double in mass every 2-3 days. Protein content is 17%. Needs only a few inches of water, sunlight and trace minerals. I've done the math,…
